Can't sent environment variables to EB due to ERROR: InvalidSyntaxError

[StubbornDeer]

Description

EB SETENV doesn't allow to send variables. Even this string shows the error "ERROR: InvalidSyntaxError - You must use the format KEY=VALUE to set an environment variable. Variables must start with a letter."

eb setenv FLASK_APP=commands

Steps to reproduce

In my VS Code terminal, on the computer with EB installed, just run this command.

Observed result

Expected result

Env variables should be sent to EB

Additional environment details (Ex: Windows, Mac, Amazon Linux etc)

Tried to debug the code, in setenv.py I see the pargs is not right:

    def do_command(self):
        app_name = self.get_app_name()
        env_name = self.get_env_name()
        var_list = self.app.pargs.varKey
        timeout = self.app.pargs.timeout
        
        print('COMMANDS', self.app.pargs.varKey)

        envvarops.setenv(app_name, env_name, var_list, timeout)
